Earlier this week, Alec Baldwin applied for a marriage license with his girlfriend Hilaria Thomas. On his way out of the courthouse the volatile actor then got into a violent altercation with a photographer.

So obviously Baldwin had a lot to talk about during his appearance on 'Late Night With David Letterman' Wednesday night. But, perhaps in an attempt to divert some of the attention from his paparazzi dust up, the '30 Rock' star did something rarely seen on TV. He dropped his pants. Being a good sport, Letterman followed up by doing the same. Check out some (awkward) celebrity skin.

Baldwin's reason for dropping trou was to demonstrate the waist-shrinking results of his new, possibly pre-material, diet.

If you're still wondering what happened between him and photographer, Baldwin did address that too. Watch his humorous take on the incident below.
